Patented Dec. 16, 1930 UNITED STATES GEORGE D. COX, F PHILADELPHIA, PENNSYLVANIA MEMORANDUM TICKET For TELEBI-IONE SERVICE Application filedMarch 19, 1.930. Serial No. 437,179.

My device has reference to the tickets or checking slips that are usedin telephone exchanges to carry the necessary information from theoperator at the board to the place where these checks or tickets are tobe collected and used. These tickets have spaces for information ofvarying kinds. Some of these blanks are filled by the operator at theboard. Others are filled elsewhere. It often happens that the ticketmust pass through several hands before its spaces are filled. Many ofthe operations have to be performed very quickly and under pressure fortime.

The trouble has been that an expeditious way of performing the necessaryoperations was dilficult to devise. An ordinary memorandum slip enclosedin a container and placed in a pneumatic tube required far too much timeto prepare and use. Many attempts to use the ticket by itself in thetubes were failures owing tothe paper or card bending or the tube notbeing fitted to receive the ticket or the ticket suitably shaped to thetube. Frequently the tickets stuck and clogged the tube, and had to beforced out by a chaser or even'the tube opened, often in veryinconvenient locations.

I have used a tube rectangular in crosssection, and used with it aticket of a very particular form and construction, which fillscompletely the whole of the tube and made it of a material havingpeculiarities and treated in a particular way, and having a particularshape. It fills also the other requisites for use at a telephoneswitchboard,

such as accessibility to the operator and compactness in packing. Thesepeculiarities will be set forth in detail below.

Fig. 1 is a side elevation of the lower portion of a tube showing indotted outlines the position of an entering ticket. Fig. 2 is a bottomplan of the same. Fig. 3 is a section on line 33 of Fig. 2. Fig. 4 showsthe face of a ticket in position for writing upon. Fig. 5 a sideelevation of the "same. Fig. 6 is a section on line 66 of Fig. 1. Fig. 7is a front view of a ticket pack, and Fig. 8 is a side view of same.

The pneumatic tube 1 having an oblong cross section in practicallyrectangular shape sary elasticity andresiliency so that the flap 13 willhow when inserted in the tube 1 and enables a ticket that has a width tofit snugly into the interior width of the tube along its longer side,and a flap of the samewidth, long enough to extend across the tube andhave the end a lie against the side opposite that on which the body 2 ofthe ticket rests. This flap 3 so placed closes the tube and forms apiston that under the air pressure drives the ticket through the tube 1.

The special material and construction of 16. the ticket to enable it toperform its functions are these. It ismade of uncalendered paper, withlong fibres substantially all running'the lengthof the ticket. Thisgives it the necesspring openfiat when it has emerged from it.

Theline of theloend 6, extending across the face of the ticket runsacross the fibre of the paper and is directly at right angleswith theside edges a, a, of the ticket. Bearing in mind the necessity of theticket performing the function of a piston, the importance that exceedthe breadth of the tube to an extent sufficient to close completely .thetube. and cause the flaps edge cl to be turned down and lie snuglyagainst the inside wall ofthe tube. But-the material of the flap must beresilient enough to keep the friction of the ticket 'in the tube fromholding back the ticket sufficiently to invertthe flap, for in this casethe next ticket'would probably stick and the tube soon become clogged.The fold or hinge between the main body of the ticket and this flap ispreferably formed by cutting the ticket from the back side partlythrough the fabric of the paper leaving the front face intact. This doesnot crush the fabric as a folding over would, leaves the front sidesmooth and fiat and does not weaken or crush the fibres of the paper. Ahinge b of this character crossing strongly fibred paper is stronger andless liable to tear than where the fold is bent and the turned overparts crushed down on each other. The construction of the ticket alsolends itself to the standard stacking and packing. The tickets arestacked and packed as shown in Fig. 8 and are thenplaced on theoperators table in the form shown in Fig. 7 She takes a ticket from thepack shown in Fig. 7, and can flip it open by her little finger andplace it at hand partly unfolded, as

shown in Figs. land 5. She can then insert it in the tube as shown inFigs. 1, 2, 3, and 6, and it will instantly be carried to itsdestination.

These tickets can have any configuration desired and blanks for thevarious entries needed in telephone management. The figures on thesevary with their particular use. Frequently two or three only of theblanks are filled in .at the switchboard, others are filled in at thefirst destination, and the tickets sent through another tube to a seconddestination, or evena third, before all blanks are fillGd. I Y

My device'is a small one and the requirementsare very particular to meeta particular use, and while I do not claim tickets that vary inconstruction from that defined above, particularly when intended for asomewhat different use, I believe I am entitled to considerpurely.formal changes as within patent.

Ijclaimz I r 1. In a telephone memorandum distribution system whereintickets containing memoranda are transmitted through pneumatic tubesrectangular in cross section, a

ticket. made of uncalendered fibered paperhaving the fibre runninglengthwise of the tickets, ofa width corresponding to the longest widthof the inside section of the tube, and consisting of a main bodyportion,

and a flap, the width of which exceeds slightly the breadth of therectangular cross section of the said tube, and having the'hinge betweenthe main body of the ticket and the flap running at right angles withthe side edges of the flap and across the fibre of the paper. V V

2. The device as defined in claim 1, wherein the hinge for connectingthe main body and thefiap of the ticket is formed'by a cut passing partway. through the material of the ticket from the rearface of the ticket.
